Sometimes you wonder what people think of you when they give you certain gifts. Last Christmas, I received a paperback book called THE KNOW-IT-ALL by A.J. Jacobs. It was originally published in 2004, but I had never heard of it. At first glance of the title, I pondered whether the giver of said book was trying to tell me something. I deplore Know-It-Alls. Is there anything more annoying than someone who believes that have reached the limits of knowledge and wisdom? There are, in fact, no such things as Know-It-Alls. Only people who think they are. So when I sat down and unwrapped THE KNOW-IT-ALL, it stung a little. Was this my friend’s subtle way of holding a mirror up to me, gazing at my own reflection as if it was, as Norman Mailer once wrote, “a stranger’s art”? Was I obnoxiously a Know-It-All, but paradoxically, didn’t know it? But then I looked at the little card that accompanied the book and it read simply: “You’re the curious type. You might like this book. Merry Christmas”.
